Dating - They cannot be a billion years old, or close to that figure. At greater depths, carbon dioxide can have more effect: at depths to about 200 km, the temperatures of initial melting of a carbonated peridotite composition were determined to be 450 °C to 600 °C lower than for the same composition with no carbon dioxide.

Much later after the Grand canyon was already formed, igneous rocks were formed from a volcano on top of the canyon, that Indians saw erupt, only about 1000 years ago. The slope of the line is used to determine the age of the sample. Wiens received a bachelor's degree in Physics from Wheaton College and a PhD from the University of Minnesota, doing research on meteorites and moon rocks.

The lead and helium results suggest that rates of radioactive decay may have been much higher in the recent past. Interesting insights are likely to come from such a group.
